Dear Deardrie, My boyfriend's a right dick! He told me the best cure for constipation was anal sex. I didn't believe him but after some persuasion, he talked me into it and I let him stick his big fat cock into my tiny little arsehole. He shagged me up the bum really hard then after a while, shot his muck, deep into my bowels. He's just rung me this morning saying he wants to try it again as he's still constipated. What should I do?
